Slideshow: Katy Perry at House of Blues Katy Perry brought her debut headlining tour, "Hello Katy" -- and her larger-than-life stage-prop cat, Katy Purry -- to Boston's House of Blues. Highlights: a pussy joke, a period joke, a watermelon with the word "penis" on it, and a bunch of other certified borscht-belt blue humor that left the pre-teens in the audience cackling, and their moms looking horrified . . . that is, when said MILFs weren't losing their shit to "Hot and Cold."
